-------------------------------
Summary: Manage and share gateways of taskmanagers between jobs in
session cluster
Key: FLINK-25334
URL: https://issues.apache.org/jira/browse/FLINK-25334
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Affects Versions: 1.13.3, 1.12.4, 1.14.0
Reporter: Shammon
Flink session cluster launches a certain number of taskmanagers and they won't
exit during the cluster running. When a job is submitted to the cluster,
taskmanagers will offer slots to `JobMaster` with location info. Then
`JobMaster` will get `InetAddress` from the location and connect the
taskmanager. This cause some performance loss and it isn't necessary in session
cluster.
It's better to manager the gateways of taskmanagers in JM and share them
between jobs. When a taskmanager's gateway is exist and valid, the `JobMaster`
can use it directly instead of creating a new one.
